WILLIAM HARTLEY PUGH, OF CINCINNATI, OHIO.

\NiNDOW-FASTENING.

SPECIFICATION forming part of Letters Patent No. 666,354, dated January 22, 1901.

Application filed October 5, 1900. Serial No. 32,106. (No model.)

To ctZZ whom it ntcty concern.-

Be it known that 1, WILLIAM HARTLEY PUGH, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvementsin \Vindow-Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in fastening devices for windows.

One of the objects is to provide a reliable fastening device by means of which the window may be fastened when partly open as well as when closed.

Another object is to provide a window-fastening device which cannot be reached or manipulated from the outside.

Another object is to provide a strong, simple, and reliable window-fastening device.

My invention also consists in certain details of form and combination all of which will be more fully set forth in the description of the accompanying drawings, in which Figure 1 is a perspective view of a part of a window-sash with my improved fastening device in use. Fig. 2 is a central vertical section through a portion of the lower sash and the attached locking device on line m 00 of Fig. 3. Fig. 3 is a central vertical section through the same on line 5 z of Fig. 2. Fig. 4 is a perspective view of the connecting or looking bar. Fig. 5 is a perspective view of one of the socket-plates, which is attached to the upper sash. Fig. 6 is a central vertical section through the same on line '0 'v of Fig. 5. Fig. '7 is a perspective view of the base or swivel plate. Fig. 8 is a perspective view of the button for holding the lockingbar in contact with the socket-plate.

A represents the window-frame, in which are mounted an upper sash B and a lower sash O in the usual manner.

D represents a swivel-plate preferably attached to the upper edge of the lower sash by means of screws E.

F represents a semispherical metal block swiveled to the journal-plate by means of the stud-screw G.

H represents a T-shaped gain conforming to the curved surface of the block.

I represents the lock-bar, the lower end I of which is T-shaped and curved, so as to engage the gain in the face of the block F. The opposite end of the locking-bar has a cross-head J, which is adapted to engage a similar-shaped recess in the plate K, of which there may be one or more located one above the other along the sideof the upper windowsash.

L represents a button which is pivoted to the plate K and when pushed into position above the cross-head J prevents the disengagement of the lock-bar from the recess in the plate K.

When the lock-bar is not in use, the block F is turned on its center at right angles to the position Fig. 1 and the bar I dropped down out of the way, as shown in dotted line, Fig. 2.

It will be noted that my locking-bar is adapted to resist either a thrust or pull. It will be noted, however, that from the nature of the device any attempt to enter from the outside would subject the locking device to a thrust strain instead of a pull, as is the case with window-locks heretofore in use, and that the window can only be opened by breaking the bar; also, that it cannot be reached and manipulated by a device from the outside, as with many of the fastening devices heretofore in use. By having several of the plates K along the side of the upper sash I am enabled to lock the sashes together with one of them open to any desired extent.

Having described my invention, what I claim is- 1. In a window-fastening, a block attached to one of the window-sashes and swiveled thereto; a lock-bar secured to said block by means of a lug upon one of the members engaging and sliding in a curved slot in the face of the opposite member; and a recessed plate secured to the opposite sash and adapted to engage the opposite end of the locking-bar, to lock the sashes together.

2. In awindow-fastening, ablock swiveled to one of the window-sashes; a lock-bar seated and adapted to slide in a curved gain in the face of the swiveled block, a plate secured to the opposite sash and provided with a re- 10 engage a cross-head on the opposite end of the lock-bar, and a button adapted to hold the cross-head in the recess, substantially as specified.

In testimony whereof I have aflixed my signature in presence of two Witnesses.

WILLIAM HARTLEY PUGI'I.
